Question

Find the least number which must be subtracted from 1949 we get a perfect square number​

Answer 1

Answer:

1989

We know that, if we subtract the remainder from the number, we get a perfect square.

Here, we get the remainder 53. Therefore 53 must be subtracted from 1989 to get a perfect square.

therefore 1989-53=1936∴1989−53=1936

Hence, the square root of 1936 is 44.
